What elements do the earth sun and moon have in common?

All elements that occur in nature occur on Earth, the Sun, and the Moon - but the proportions are different. The main difference is that the Sun is made up mainly of hydrogen and helium; both are relatively scarce on Earth and on the Moon.


How many different kinds of atoms occur naturally on earth and why so?

There are 118 different kinds of atoms that occur naturally on Earth, known as elements. This is because of the unique number of protons in the nucleus of each atom, which determines the element's identity. The various combinations of protons, neutrons, and electrons give rise to the different elements found in nature.

True. Mendeleev organized the elements into the periodic table based on their atomic weight and similar chemical properties. He noticed that elements with similar properties tended to occur at regular intervals, leading to the periodicity of the elements.


Why can elements be produced in the sun but not in earths atmosphere?

Elements can be produced in the sun through nuclear fusion reactions that occur due to the intense heat and pressure. These conditions are not present in Earth's atmosphere, which is why elements are not produced there. Earth's atmosphere primarily consists of gases and does not contain the necessary conditions for nuclear fusion to occur.


Is it true that the elements found in magma are quite different from those found in earths crust?

Yes, the elements found in magma and the Earth's crust can be different due to the melting and differentiation processes that occur in the Earth's interior. While both can contain common elements, the magma tends to have higher concentrations of elements that preferentially partition into the melt during melting processes, leading to some differences in composition.
